CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is a continuation in part application of aninternational application No. PCT/CN2016/090037, filed on Jul. 14, 2016,which claims priority to Chinese Patent Application No. 201510439751.8,filed on Jul. 23, 2015, the contents of both of which are hereinincorporated by reference in their entireties.

TECHNICAL FIELD

The present disclosure relates to electronic technology field andparticularly relates to a method for adjusting a screen displayingdirection and a terminal.

BACKGROUND

With the development of science technology, the display screen of aterminal becomes larger and larger, and functions of the terminal aremore and more diversified. Among the functions of the terminal, playingvideo is the most basic one. In the process of playing video, since theplacement state of the terminal varies, the screen displaying directionof the terminal needs to be adjusted, so that to obtain a better viewingeffect. A traditional manner to adjust the screen displaying directionis to set the screen displaying direction in a menu of the terminal,however, the operating procedure thereof is complex; besides, a userneeds to stop playing the video to set the screen displaying direction,which affects the video viewing effect.

The terminal is disposed with a gravity sensor in the related art, andthe gravity sensor is used to detect in every period whether theorientation of the terminal is changed, so as to adjust displaydirection of the screen. For example, the gravity sensor detects inevery period whether the orientation of the terminal is changed, if YES,the gravity sensor detects the orientation of the terminal after thechange and the screen displaying direction can be adjusted in time.However, due to the high sensitivity of the gravity sensor, vibration ofthe terminal caused by disturbance may result in misjudgment of thegravity sensor, which can change screen displaying direction, and as aresult, user experience is reduced.

Referring to FIG. 1, FIG. 1 is a schematic flowchart illustrating animplementation of a method for adjusting a screen displaying directionof the present disclosure. Methods according to implementations of thepresent disclosure can be implemented by a terminal, which can be amobile phone, tablet PC, laptop, pocket PC, mobile internet device(MID), wearable device (such as a smart watch), smart bracelet,pedometer and the like) or other terminals whose screen displayingdirection can be adjusted.

A method is provided according to implementations of the presentdisclosure. In this method, an authority fingerprint is acquired, andthe authority fingerprint is a fingerprint having the authority ofchanging the screen displaying direction; when a first fingerprint isacquired, it is judged whether the first fingerprint is the authorityfingerprint; if the first fingerprint is the authority fingerprint, aninput direction of the first fingerprint is acquired; the screendisplaying direction is adjusted according to the input direction of thefirst fingerprint. The method will be described in detail in combinationwith implementations below.

As illustrated in FIG. 1, a method for adjusting a screen displayingdirection according to an implementation of the present disclosure canbegin at block 100.

At block 100, at least one authority fingerprint is acquired, and theauthority fingerprint is a fingerprint having the authority of changingthe screen displaying direction. The term “authority fingerprint” usedherein can refer to one authority fingerprint or a plurality ofauthority fingerprints, the present disclosure is not limited thereto,and the quantity thereof can be set according to actual needs. In thefollowing, for case of explanation, take one authority fingerprint as anexample.

In specific implementations, the terminal can acquire at least onefingerprint, for example, the terminal can acquire a second fingerprintand a third fingerprint input by a first user, and the first user can bea user to whom the terminal belongs. The second fingerprint acquired bythe terminal can be a fingerprint of the right index finger, the thirdfingerprint can be a fingerprint of the left index finger. The terminalcan also set the second fingerprint as the authority fingerprintaccording to settings of a user, the authority fingerprint has theauthority of changing the screen displaying direction. When thefingerprint of the right index finger of the first user is recognized,the terminal enters a state of changing the screen displaying direction.

As an implementation, the terminal can also set the third fingerprint asa fingerprint having other functional authorities according to settingsof the user.

As an implementation, the terminal can allow other users to input afingerprint that has the authority of changing the screen displayingdirection. For example, the terminal can receive a fourth fingerprintinput by a second user, and set the fourth fingerprint as a fingerprinthaving the authority of changing the screen displaying directionaccording to settings of any user (the first user or the second user).The terminal can also receive a fifth fingerprint input by a third user,and set the fifth fingerprint as a fingerprint having the authority ofchanging the screen displaying direction according to settings of anyuser (the first user, the second user, or the third user). Screendisplaying direction changed by different authority fingerprints variesand can be set according to settings of users.

At block 101, a first fingerprint is acquired.

In specific implementations, when the first fingerprint is acquired, itis judged whether the first fingerprint is the authority fingerprint.

In specific implementations, after setting authority fingerprints andscreen displaying directions corresponding to the authorityfingerprints, the terminal can acquire a fingerprint via a fingerprintsensor. The manner of acquiring fingerprints by the fingerprint sensorof this implementation can be sliding. Because of small occupied area, asliding fingerprint sensor is more flexible for product design, so thatit is widely deployed on a variety of smaller electronic terminals. Whena finger of the user slides over the surface of the fingerprint sensor,the terminal can acquire clear fingerprint details and seize fingerprintfeatures via scanning or a series of snapshot. When the firstfingerprint has been acquired, the terminal judges whether the firstfingerprint is the authority fingerprint according to seized fingerprintfeatures, namely, judges whether the first fingerprint is one of thesecond fingerprint input by the first user, the fourth fingerprint inputby the second user, and the fifth fingerprint input by the third userand therefore has the authority of changing the screen displayingdirection; if so, the terminal acquires an input direction of the firstfingerprint; otherwise, the process ends, and the terminal does notperform any operation about changing the screen displaying direction, orthe terminal judges whether the first fingerprint is a fingerprinthaving other functions.

At block 102, when the first fingerprint is the authority fingerprint,an input direction of the first fingerprint is acquired.

In specific implementations, after determining that the firstfingerprint is the authority fingerprint, the terminal can judge thatthe first fingerprint is one of the second fingerprint input by thefirst user, the fourth fingerprint input by the second user, and thefifth fingerprint input by the third user, and the terminal can acquirea sliding direction of the finger of the user as well as an inputdirection of the fingerprint via the fingerprint sensor.

At block 103, the screen displaying direction is adjusted according tothe input direction of the first fingerprint.

In specific implementations, the case where the terminal determines thefirst fingerprint acquired is the second fingerprint input by the firstuser is taken as an example, after the first user sets the secondfingerprint to be the authority fingerprint, the terminal can presetcorresponding screen displaying directions for each input direction ofthe second fingerprint according to settings of the first user. When aninput direction of the first fingerprint has been acquired, the terminalcompares the acquired input direction of the first fingerprint withpreset input directions of the second fingerprint one by one. Forexample, the user presets input direction#1, input direction#2, inputdirection#3, and input direction#4 for the second fingerprint, theterminal compares the acquired input direction of the first fingerprintwith the above-mentioned four input directions of the second fingerprintone by one. If the terminal finds out that the input direction of thesecond fingerprint that is the same as the input direction of the firstfingerprint is input direction#4 of the second fingerprint, the terminalfinds the screen displaying direction corresponding to input direction#4of the second fingerprint, and then adjusts the current screendisplaying direction of the terminal to the screen displaying directioncorresponding to input direction#4 of the second fingerprint.

In addition, in some implementations of the present disclosure, aterminal can execute the following procedures to adjusting the screendisplaying direction: the terminal acquires a first fingerprint. Thenthe terminal acquires an input direction of the first fingerprint. Atlast, the terminal adjusts the screen displaying direction according tothe input direction of the first fingerprint.

By means of implementations of the present disclosure, an authorityfingerprint is acquired, and the authority fingerprint is a fingerprinthaving the authority of changing a screen displaying direction; when afirst fingerprint is acquired, it is judged whether the firstfingerprint is the authority fingerprint, if so, an input direction ofthe first fingerprint is acquired and the screen displaying direction isadjusted according to the input direction of the first fingerprint.Besides, the authority fingerprint for changing the screen direction canbe preset. When the first fingerprint is acquired, if the firstfingerprint is the authority fingerprint, the screen displayingdirection is adjusted according to the input direction of the firstfingerprint, so that a timing for adjusting the screen displayingdirection can be judged accurately, and the accuracy of adjusting thescreen displaying direction can be improved.

Referring to FIG. 2, FIG. 2 is a schematic flowchart illustratinganother implementation of the method for adjusting a screen displayingdirection of the present disclosure. Methods according toimplementations of the present disclosure can be implemented by aterminal, which can be a mobile phone, tablet PC, laptop, pocket PC,mobile internet device (MID), wearable device (such as a smart watch),smart bracelet, pedometer and the like) or other terminals whose screendisplaying direction can be adjusted.

As illustrated in FIG. 2, a method for adjusting a screen displayingdirection according to another implementation of the present disclosurecan begin at block 200.

At block 200, an authority fingerprint is acquired, and the authorityfingerprint is a fingerprint having the authority of changing the screendisplaying direction.

In specific implementations, the terminal can acquire at least onefingerprint, for example, the terminal can acquire a second fingerprintand a third fingerprint input by a first user, and the first user can bea user to whom the terminal belongs. The second fingerprint acquired bythe terminal can be a fingerprint of the right index finger, the thirdfingerprint can be a fingerprint of the left index finger. The terminalcan also set the second fingerprint as the authority fingerprintaccording to settings of the first user, the authority fingerprint hasthe authority of changing the screen displaying direction. When thefingerprint of the right index finger of the first user is recognized,the terminal enters a state of changing the screen displaying direction.

As an implementation, the terminal can also set the third fingerprint asa fingerprint having other functional authorities according to settingsof the user.

As an implementation, the terminal can receive fingerprints input byother users, these fingerprints also have the authority of changing thescreen displaying direction. For example, the terminal can receive afourth fingerprint input by a second user, and set the fourthfingerprint as a fingerprint having the authority of changing the screendisplaying direction according to settings of any user (the first useror the second user). The terminal can also receive a fifth fingerprintinput by a third user, and set the fifth fingerprint as a fingerprinthaving the authority of changing the screen displaying directionaccording to settings of any user (the first user, the second user orthe third user). Screen displaying direction changed by differentauthority fingerprints varies, the details can be set according tosettings of users.

As an implementation, the terminal can acquire a fingerprint via afingerprint sensor. The manner of acquiring fingerprints by thefingerprint sensor of this implementation can be sliding. Because ofsmall occupied area, a sliding fingerprint sensor is more flexible forproduct design, so that it is widely deployed on a variety of smallerelectronic terminals. When a finger of the user slides over the surfaceof the fingerprint sensor, the terminal can acquire clear fingerprintdetails, seize fingerprint features and acquire input directions of afingerprint via scanning or a series of snapshot.

At block 201, input directions of the authority fingerprint are acquiredand stored.

In specific implementations, take the case where the terminal sets thesecond fingerprint input by the first user to be the authorityfingerprint as an example. After setting the second fingerprint input bythe first user to be the authority fingerprint, the terminal can acquiredifferent input directions of the second fingerprint and then setcorresponding screen displaying directions according to different inputdirections of the second fingerprint.

At block 202, screen displaying directions corresponding to inputdirections of the authority fingerprint are determined.

In specific implementations, as illustrated in FIG. 3, if the inputdirection of the second fingerprint on the fingerprint sensor is slidingfrom the first end of the fingerprint senor to the third end of thefingerprint sensor, the corresponding screen displaying direction can beset as the vertical direction towards the third end of the fingerprintsensor. As illustrated in FIG. 4, if the input direction of the secondfingerprint on the fingerprint sensor is sliding from the fourth end ofthe fingerprint senor to the second end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the second end of the fingerprint sensor. Asillustrated in FIG. 5, if the input direction of the second fingerprinton the fingerprint sensor is sliding from the second end of thefingerprint senor to the fourth end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the fourth end of the fingerprint sensor. Asillustrated in FIG. 6, if the input direction of the second fingerprinton the fingerprint sensor is sliding from the third end of thefingerprint senor to the first end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the first end of the fingerprint sensor.

It should be noted that, the above-mentioned process of settingdifferent corresponding screen displaying directions for different inputdirections of the second fingerprint is only an example, theimplementations of the present disclosure has no restriction on thecorrespondence between input directions of fingerprints and screendisplaying directions. For example, if the input direction of the secondfingerprint on the fingerprint sensor is sliding from the first end ofthe fingerprint senor to the third end of the fingerprint sensor, thecorresponding screen displaying direction can also be set as one of avertical direction towards the second end of the fingerprint sensor, thevertical direction towards the fourth end of the fingerprint sensor, andthe vertical direction towards the first end of the fingerprint sensor.

At block 203, a first fingerprint is acquired; when the firstfingerprint is the authority fingerprint, the terminal proceeds to block204; otherwise, the terminal proceeds to block 205.

In specific implementations, when the first fingerprint is acquired, itis judged whether the first fingerprint is the authority fingerprint.

In specific implementations, after the terminal acquires authorityfingerprints and determines screen displaying directions correspondingto the authority fingerprints, the fingerprint sensor can enter a sleepstate; in this situation, the system power consumption of thefingerprint sensor is at microampere level, and it has minimal effectson system efficiency. When the first user inputs the first fingerprintto the fingerprint sensor of the terminal, the fingerprint sensorrecovers from the sleep state to an operating state immediately. In thissituation, a chip of the fingerprint sensor or a fingerprintidentification software module of the fingerprint sensor acquires clearfingerprint details and seize fingerprint features via scanning or aseries of snapshot. When the first fingerprint has been acquired, theterminal judges whether the first fingerprint is the authorityfingerprint according to seized fingerprint features, namely, judgeswhether the first fingerprint is one of the second fingerprint input bythe first user, the fourth fingerprint input by the second user, and thefifth fingerprint input by the third user and therefore has theauthority of changing the screen displaying direction; if so, theterminal acquires an input direction of the first fingerprint;otherwise, the terminal prompts to set the first fingerprint to be theauthority fingerprint. For example, when the first fingerprint has beenacquired, the terminal compares the first fingerprint with thepre-stored second fingerprint, the pre-stored fourth fingerprint, andthe pre-stored fifth fingerprint one by one, if the first fingerprint isthe same as one of the pre-stored authority fingerprints (for example,the first fingerprint is the same as the second fingerprint of theauthority fingerprints), an input direction of the first fingerprint isacquired; otherwise, the terminal prompts to set the first fingerprintto be the authority fingerprint; alternatively, the terminal will notperform any operation about changing the screen displaying direction, orthe terminal judges whether the first fingerprint is a fingerprinthaving other functions.

At block 204, an input direction of the first fingerprint is acquired.

In specific implementations, after determining that the firstfingerprint is the authority fingerprint, the terminal further acquiresa sliding direction of the finger of the user, namely the inputdirection of the first fingerprint.

At block 205, a first prompting message is output, the first promptingmessage can be used to prompt to set the first fingerprint as theauthority fingerprint and prompt to input the input direction of thefirst fingerprint so as to determine a screen displaying directioncorresponding to the input direction of the first fingerprint.

In specific implementations, if judging that the first fingerprint isnot one of the pre-stored second fingerprint, the pre-stored fourthfingerprint, and the pre-stored fifth fingerprint and therefore is notthe authority fingerprint, the terminal outputs the first promptingmessage, so as to prompt the user to set the first fingerprint as theauthority fingerprint and then acquire the input direction of the firstfingerprint, so that a screen displaying direction corresponding to theinput direction of the first fingerprint can be determined.

At block 206, when the input direction of the first fingerprint is thesame as a pre-stored input direction of the authority fingerprint, theterminal proceeds to block 207; otherwise, the terminal proceeds toblock 208.

In specific implementations, it is judged whether the input direction ofthe first fingerprint is the same as the input direction of thepre-stored authority fingerprint.

In specific implementations, after acquiring the input direction of thefirst fingerprint, the terminal judges whether the input direction ofthe first fingerprint is one of the input directions of the secondfingerprint illustrated in FIG. 3 to FIG. 6, if so, the terminalproceeds to block 207 to look for a screen displaying directioncorresponding to the input direction of the second fingerprint;otherwise, such as illustrated in FIG. 7, the input direction of thefirst fingerprint is an angular direction between the second end of thefingerprint sensor and the third end of the fingerprint sensor, theterminal proceeds to block 208 and the process ends.

At block 207, the screen displaying direction is adjusted to a directioncorresponding to the input direction of the pre-stored authorityfingerprint according to the input direction of the pre-stored authorityfingerprint.

In specific implementations, since the first fingerprint is the same asthe pre-stored second fingerprint, after acquiring the input directionof the first fingerprint, the terminal matches the input direction ofthe first fingerprint with the input direction of the pre-stored secondfingerprint, and then finds a corresponding screen displaying directionaccording to the matching input direction of the second fingerprint. Forexample, after matching by the terminal, if the input direction of thefirst fingerprint is the same as the input direction of the secondfingerprint illustrated in FIG. 4, namely, if the input direction of thefirst fingerprint is sliding form the fourth end of the fingerprintsensor to the second end of the fingerprint sensor, the correspondingscreen displaying direction is the vertical direction towards the secondend of the fingerprint sensor, so that the terminal adjusts the currentscreen displaying direction to the vertical direction towards the secondend of the fingerprint sensor.

At block 208, the process ends.

In specific implementations, it is judged at block 206 that the inputdirection of the first fingerprint is not the same as the inputdirection of the pre-stored authority fingerprint, the process ends, theterminal stops looking for the screen displaying direction correspondingto the input direction of the first fingerprint, and the terminal canprompt the first user to enter the first fingerprint again, or theterminal can look for other function options corresponding to this inputdirection and execute operations corresponding to other functionoptions.

By means of implementations of the present disclosure, an authorityfingerprint is acquired, and the authority fingerprint is a fingerprinthaving the authority of changing a screen displaying direction; when afirst fingerprint is acquired, it is judged whether the firstfingerprint is the authority fingerprint, if so, an input direction ofthe first fingerprint is acquired and the screen displaying direction isadjusted according to the input direction of the first fingerprint.Besides, the authority fingerprint for changing the screen direction canbe preset. When the first fingerprint is acquired, if the firstfingerprint is the authority fingerprint, the screen displayingdirection is adjusted according to the input direction of the firstfingerprint, so that a timing for adjusting the screen displayingdirection can be judged accurately, and the accuracy of adjusting thescreen displaying direction can be improved.

Comparing FIG. 2 with FIG. 1, the operations at block 200, block 203,and block 204 of FIG. 2 can correspond to those at block 100, block 101,and block 102 of FIG. 1 respectively, and on the basis of FIG. 1, FIG. 2further provides an implementation for the screen displaying directionadjustment. In the method illustrated in FIG. 2, the input directions ofthe authority fingerprint are acquired and stored, and screen displayingdirections corresponding to input directions of the authorityfingerprint are determined. Subsequently, the screen displayingdirection adjustment can be accomplished based on the comparison betweenthe input direction of the authority fingerprint and the input directionof the first fingerprint.

Besides, in the method illustrated in FIG. 2, the input direction of thefirst fingerprint should match with the input direction of thepre-stored authority fingerprint in order to accomplish the screendisplaying direction adjustment, so as to avoid triggering the screendisplaying direction adjustment accidentally.

Referring to FIG. 8, FIG. 8 is a schematic flowchart illustratinganother implementation of a method for adjusting a screen displayingdirection of the present disclosure. Methods according toimplementations of the present disclosure can be implemented by aterminal, which can be a mobile phone, tablet PC, laptop, pocket PC,mobile internet device (MID), wearable device (such as a smart watch),smart bracelet, pedometer and the like) or other terminals whose screendisplaying direction can be adjusted.

As illustrated in FIG. 8, a method for adjusting a screen displayingdirection according to another implementation of the present disclosurecan begin at block 800.

At block 800, an authority fingerprint is acquired, and the authorityfingerprint is a fingerprint having the authority of changing the screendisplaying direction.

In specific implementations, the terminal can acquire at least onefingerprint, for example, the terminal can acquire a second fingerprintand a third fingerprint input by a first user, and the first user can bea user to whom the terminal belongs. And the second fingerprint acquiredby the terminal can be a fingerprint of the right index finger, thethird fingerprint can be a fingerprint of the left index finger. Theterminal can also set the second fingerprint as the authorityfingerprint according to settings of the first user, the authorityfingerprint has the authority of changing the screen displayingdirection. When the fingerprint of the right index finger of the firstuser is recognized, the terminal enters a state of changing the screendisplaying direction.

At block 801, input directions of the authority fingerprint are acquiredand stored.

In specific implementations, take the case where the terminal sets thesecond fingerprint input by the first user as the authority fingerprintas an example, after setting the second fingerprint input by the firstuser as the authority fingerprint, the terminal can acquire differentinput directions of the second fingerprint, and then, set correspondingscreen displaying directions according to input directions of the secondfingerprint.

At block 802, screen displaying directions corresponding to inputdirections of the authority fingerprint is determined.

In specific implementations, as illustrated in FIG. 3, if the inputdirection of the second fingerprint on the fingerprint sensor is slidingfrom the first end of the fingerprint senor to the third end of thefingerprint sensor, the corresponding screen displaying direction can beset as the vertical direction towards the third end of the fingerprintsensor. As illustrated in FIG. 4, if the input direction of the secondfingerprint on the fingerprint sensor is sliding from the fourth end ofthe fingerprint senor to the second end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the second end of the fingerprint sensor. Asillustrated in FIG. 5, if the input direction of the second fingerprinton the fingerprint sensor is sliding from the second end of thefingerprint senor to the fourth end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the fourth end of the fingerprint sensor. Asillustrated in FIG. 6, if the input direction of the second fingerprinton the fingerprint sensor is sliding from the third end of thefingerprint senor to the first end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the first end of the fingerprint sensor.

It is noted that, the above-mentioned process of setting screendisplaying directions corresponding to different input directions of thesecond fingerprint is only an example, implementations of the presentdisclosure set no restriction on the corresponding relation betweeninput directions of fingerprints and screen displaying directions. Forexample, if the input direction of the second fingerprint on thefingerprint sensor is sliding from the first end of the fingerprintsenor to the third end of the fingerprint sensor, the correspondingscreen displaying direction can also be set as any direction of thevertical direction towards the second end of the fingerprint sensor, thevertical direction towards the fourth end of the fingerprint sensor andthe vertical direction towards the first end of the fingerprint sensor.

At block 803, a first fingerprint is acquired; when the firstfingerprint is the authority fingerprint, the terminal proceeds to block804, otherwise, the terminal proceeds to block 805.

In specific implementations, when the first fingerprint is acquired, itis judged whether the first fingerprint is the authority fingerprint.

In specific implementations, after the terminal acquires authorityfingerprints and determines screen displaying directions correspondingto the authority fingerprints, the fingerprint sensor can enter a sleepstate; in this situation, the system power consumption of thefingerprint sensor is at microampere level, and it has minimal effectson system efficiency. When the first user inputs the first fingerprintto the fingerprint sensor of the terminal, the fingerprint sensorrecovers from the sleep state to an operating state immediately. In thissituation, a chip of the fingerprint sensor or a fingerprintidentification software module of the fingerprint sensor acquires clearfingerprint details and seize fingerprint features via scanning or aseries of snapshot. When the first fingerprint has been acquired, theterminal judges whether the first fingerprint is the authorityfingerprint according to seized fingerprint features, namely, judgeswhether the first fingerprint is one of the second fingerprint input bythe first user, the fourth fingerprint input by the second user, and thefifth fingerprint input by the third user and therefore has theauthority of changing the screen displaying direction; if so, theterminal acquires an input direction of the first fingerprint;otherwise, the terminal prompts to set the first fingerprint as theauthority fingerprint. For example, when acquiring the firstfingerprint, the terminal compares the first fingerprint with the presetsecond fingerprint, the preset fourth fingerprint and the preset fifthfingerprint one by one, if the first fingerprint is the same as one ofthe authority fingerprints (for example, the first fingerprint is thesame as the second fingerprint of authority fingerprints), an inputdirection of the first fingerprint is acquired; otherwise, the terminalprompts to set the first fingerprint as the authority fingerprint;optionally, the terminal will not perform any operation about changingthe screen displaying direction or the terminal judges whether the firstfingerprint is a fingerprint having an other functions.

At block 804, an input direction of the first fingerprint is acquired.

In specific implementations, after determining that the firstfingerprint is the authority fingerprint, the terminal further acquiresa sliding direction of the finger of the user, namely the inputdirection of the first fingerprint

At block 805, a first prompting message is output, the first promptingmessage can be used to prompt to set the first fingerprint as theauthority fingerprint and prompt to input the input direction of thefirst fingerprint so as to determine a screen displaying directioncorresponding to the input direction of the first fingerprint.

In specific implementations, if judging that the first fingerprint isnot an authority fingerprint of the pre-stored second fingerprint, thepre-stored fourth fingerprint or the pre-stored fifth fingerprint, theterminal outputs the first prompting message, so as to prompt the userto set the first fingerprint as the authority fingerprint and thenacquire the input direction of the first fingerprint, so that a screendisplaying direction corresponding to the input direction of the firstfingerprint can be determined.

At block 806, when the input direction of the first fingerprint is thesame as the input direction of the pre-stored authority fingerprint, theterminal proceeds to block 807; otherwise, the terminal proceeds toblock 810.

In specific implementations, after acquiring the input direction of thefirst fingerprint, the terminal judges whether the input direction ofthe first fingerprint is one of the input directions of the secondfingerprint illustrated in FIG. 3 to FIG. 6, if so, the terminalproceeds to block 807, and finds a screen displaying directioncorresponding to the input direction of the second fingerprint;otherwise, such as illustrated in FIG. 7, the input direction of thefirst fingerprint is an angular direction between the second end of thefingerprint sensor and the third end of the fingerprint sensor, theterminal proceeds to block 810 and the process ends.

At block 807, when the input direction of the first fingerprint is thesame as the input direction of the pre-stored authority fingerprint, thescreen displaying direction is adjusted to a direction corresponding tothe input direction of the pre-stored authority fingerprint according tothe input direction of the pre-stored authority fingerprint.

In specific implementations, since the first fingerprint is the same asthe pre-stored second fingerprint, after acquiring the input directionof the first fingerprint, the terminal matches the input direction ofthe first fingerprint with the input direction of the pre-stored secondfingerprint, and then finds a corresponding screen displaying directionaccording to the matching input direction of the second fingerprint. Forexample, after matching by the terminal, if the input direction of thefirst fingerprint is the same as the input direction of the secondfingerprint illustrated in FIG. 4, namely, if the input direction of thefirst fingerprint is sliding form the fourth end of the fingerprintsensor to the second end of the fingerprint sensor, the correspondingscreen displaying direction is the vertical direction towards the secondend of the fingerprint sensor, so that the terminal adjusts the currentscreen displaying direction to the vertical direction towards the secondend of the fingerprint sensor.

At block 808, when the first fingerprint is acquired again, a timeperiod for acquiring the first fingerprint is recorded.

In specific implementations, after adjusting the screen displayingdirection, if the first fingerprint is acquired again, the terminalrecords a time period that the first fingerprint stays on thefingerprint sensor. For example, the first user can keep the right indexfinger pressing the fingerprint sensor, such that the fingerprint sensorcan record the time period that the fingerprint of the right indexfinger (namely, the first fingerprint) stays on the fingerprint sensor.

At block 809, the size of the screen display area is adjusted accordingto the recorded time period of the first fingerprint.

In specific implementations, the terminal can set a corresponding sizeof the screen display area according to the time period that the firstfingerprint stays on the fingerprint sensor. For example, if the timeperiod that the first fingerprint stays on the fingerprint sensor is onesecond, the size of the screen display area can be set to 75% of thescreen size; if the time period that the first fingerprint stays on thefingerprint sensor is two second, the size of the screen display areacan be set to 50% of the screen size; if the time period that the firstfingerprint stays on the fingerprint sensor is three second, the size ofthe screen display area can be set to 100% of the screen size. So thatthe terminal can adjust the size of the screen display area according tothe acquired time period that the first fingerprint stays on thefingerprint sensor.

At block 810, the process ends.

In specific implementations, it is judged at block 806 that the inputdirection of the first fingerprint is not the same as the inputdirection of the pre-stored authority fingerprint, the process ends, theterminal stops looking for the screen displaying direction correspondingto the input direction of the first fingerprint, and the terminal canprompt the first user to enter the first fingerprint again, or theterminal can look for other function options corresponding to this inputdirection and execute operations corresponding to other functionoptions.

By means of implementations of the present disclosure, an authorityfingerprint is acquired, and the authority fingerprint is a fingerprinthaving the authority of changing a screen displaying direction; when afirst fingerprint is acquired, it is judged whether the firstfingerprint is the authority fingerprint, if so, an input direction ofthe first fingerprint is acquired and the screen displaying direction isadjusted according to the input direction of the first fingerprint.Besides, the authority fingerprint for changing the screen direction canbe preset. When the first fingerprint is acquired, if the firstfingerprint is the authority fingerprint, the screen displayingdirection is adjusted according to the input direction of the firstfingerprint, so that a timing for adjusting the screen displayingdirection can be judged accurately, and the accuracy of adjusting thescreen displaying direction can be improved.

Comparing FIG. 8 with FIG. 2, the operations at block 800 through block807 of FIG. 8 can correspond to those of block 200 through block 207 ofFIG. 2 respectively. In the method illustrated in FIG. 8, when the firstfingerprint is acquired again, a time period for acquiring the firstfingerprint is recorded and the size of the screen display area can beadjusted according to the recorded time period of the first fingerprint.

Referring to FIG. 9A, FIG. 9A is a schematic block diagram illustratinga terminal of an implementation of the present disclosure. The terminalillustrated in FIG. 9A includes a first acquiring module 900 (such as afingerprint sensor or other input device), a second acquiring module 902(such as a motion sensor or a fingerprint sensor), and a first adjustingmodule 903 (such as a processor). And the first acquiring module 900 andthe second acquiring module 902 can be integrated in one sensor unit,for example, in a fingerprint sensor.

The first acquiring module 900 is configured to acquire one or moreauthority fingerprints (in the following, take one authority fingerprintas an example), and the authority fingerprint is a fingerprint havingthe authority of changing a screen displaying direction; the firstacquiring module 900 is further configured to acquire a firstfingerprint.

The second acquiring module 902 is configured to acquire, when the firstfingerprint is the authority fingerprint, an input direction of thefirst fingerprint if the first judging module judges that the firstfingerprint is the authority fingerprint.

The first adjusting module 903 is configured to adjust the screendisplaying direction according to the input direction of the firstfingerprint.

In specific implementations, the terminal can acquire at least onefingerprint, for example, the terminal can acquire a second fingerprintand a third fingerprint input by a first user, and the first user can bea user to whom the terminal belongs. And the second fingerprint acquiredby the terminal can be a fingerprint of the right index finger, thethird fingerprint can be a fingerprint of the left index finger. Theterminal can also set the second fingerprint as the authorityfingerprint according to settings of a user, the authority fingerprinthas the authority of changing the screen displaying direction. When thefingerprint of the right index finger of the first user is recognized,the terminal enters a state of changing the screen displaying direction.

In specific implementations, after the terminal acquires authorityfingerprints and determines screen displaying directions correspondingto the authority fingerprints, the fingerprint sensor can enter a sleepstate; in this situation, the system power consumption of thefingerprint sensor is at microampere level, and it has minimal effectson system efficiency. When the first user inputs the first fingerprintto the fingerprint sensor of the terminal, the fingerprint sensorrecovers from the sleep state to an operating state immediately. In thissituation, a chip of the fingerprint sensor or a fingerprintidentification software module of the fingerprint sensor acquires clearfingerprint details and seize fingerprint features via scanning or aseries of snapshot. When the first fingerprint has been acquired, theterminal judges whether the first fingerprint is the authorityfingerprint according to seized fingerprint features, namely, judgeswhether the first fingerprint is one of the second fingerprint input bythe first user, the fourth fingerprint input by the second user, and thefifth fingerprint input by the third user and therefore has theauthority of changing the screen displaying direction; if so, theterminal acquires an input direction of the first fingerprint;otherwise, the terminal prompts to set the first fingerprint as theauthority fingerprint. For example, when acquiring the firstfingerprint, the terminal compares the first fingerprint with the presetsecond fingerprint, the preset fourth fingerprint and the preset fifthfingerprint one by one, if the first fingerprint is the same as one ofthe authority fingerprints (for example, the first fingerprint is thesame as the second fingerprint of the authority fingerprints), an inputdirection of the first fingerprint is acquired; otherwise, the terminalprompts to set the first fingerprint as the authority fingerprint;optionally, the terminal will not perform any operation about changingthe screen displaying direction or the terminal judges whether the firstfingerprint is a fingerprint having an other functions.

In specific implementations, after determining that the firstfingerprint is the authority fingerprint, the terminal further acquiresa sliding direction of the finger of the user, namely the inputdirection of the first fingerprint.

As an implementation, as illustrated in FIG. 9B, the terminal furtherincludes a first judging module 901 (such as a processor), which isconfigured to judge whether the first fingerprint is the authorityfingerprint when the first acquiring module 900 acquires the firstfingerprint.

As an implementation, as illustrated in FIG. 10, the terminal furtherincludes a third acquiring module 904 (such as a fingerprint sensor) anda determining module 905 (such as a processor).

The third acquiring module 904 is configured to acquire and store aninput direction of the authority fingerprint. The determining module 905is configured to determine a screen displaying direction correspondingto the input direction of the authority fingerprint.

In specific implementations, take the case where the terminal sets thesecond fingerprint input by the first user as the authority fingerprintas an example, after setting the second fingerprint input by the firstuser as the authority fingerprint, the terminal can acquire differentinput directions of the second fingerprint, and then, set correspondingscreen displaying directions according to input directions of the secondfingerprint.

In specific implementations, as illustrated in FIG. 3, if the inputdirection of the second fingerprint on the fingerprint sensor is slidingfrom the first end of the fingerprint senor to the third end of thefingerprint sensor, the corresponding screen displaying direction can beset as the vertical direction towards the third end of the fingerprintsensor. As illustrated in FIG. 4, if the input direction of the secondfingerprint on the fingerprint sensor is sliding from the fourth end ofthe fingerprint senor to the second end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the second end of the fingerprint sensor. Asillustrated in FIG. 5, if the input direction of the second fingerprinton the fingerprint sensor is sliding from the second end of thefingerprint senor to the fourth end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the fourth end of the fingerprint sensor. Asillustrated in FIG. 6, if the input direction of the second fingerprinton the fingerprint sensor is sliding from the third end of thefingerprint senor to the first end of the fingerprint sensor, thecorresponding screen displaying direction can be set as the verticaldirection towards the first end of the fingerprint sensor.

It is noted that, the above-mentioned process of setting screendisplaying directions corresponding to different input directions of thesecond fingerprint is only an example, implementations of the presentdisclosure set no restriction on the corresponding relation betweeninput directions of fingerprints and screen displaying directions. Forexample, if the input direction of the second fingerprint on thefingerprint sensor is sliding from the first end of the fingerprintsenor to the third end of the fingerprint sensor, the correspondingscreen displaying direction can also be set as any direction of thevertical direction towards the second end of the fingerprint sensor, thevertical direction towards the fourth end of the fingerprint sensor andthe vertical direction towards the first end of the fingerprint sensor.

As an implementation, as illustrated in FIG. 10, the terminal furtherincludes an output module 906 (such as a display, a speaker and thelike).

The output module 906 is configured to output a first prompting messageif the first judging module judges that the first fingerprint is not theauthority fingerprint, and the first prompting message can be used toprompt to set the first fingerprint as the authority fingerprint andprompt to input the input direction of the first fingerprint so as todetermine a screen displaying direction corresponding to the inputdirection of the first fingerprint.

In specific implementations, if judging the first fingerprint is not anauthority fingerprint of the preset second fingerprint, the presetfourth fingerprint or the preset fifth fingerprint, the terminal outputsthe first prompting message, so as to prompt the user to set the firstfingerprint as the authority fingerprint and then acquire the inputdirection of the first fingerprint, so that a screen displayingdirection corresponding to the input direction of the first fingerprintcan be determined.

As an implementation, as illustrated in FIG. 10, the first adjustingmodule 903 includes a judging unit 9031 and an adjusting unit 9032.

The judging unit 9031 is configured to judge whether the input directionof the first fingerprint is the same as a pre-stored input direction ofthe authority fingerprint. The adjusting unit 9032 is configured toadjust, if he judging unit judges that the input direction of the firstfingerprint is the same as the pre-stored input direction of theauthority fingerprint, the screen displaying direction to a directioncorresponding to the pre-stored input direction of the authorityfingerprint according to the pre-stored input direction of the authorityfingerprint.

In specific implementations, after acquiring the input direction of thefirst fingerprint, the terminal judges whether the input direction ofthe first fingerprint is one of the input directions of the secondfingerprint illustrated in FIG. 3 to FIG. 6, if so, the terminal finds ascreen displaying direction corresponding to the input direction of thefirst fingerprint; otherwise, such as illustrated in FIG. 7, the inputdirection of the first fingerprint is an angular direction between thesecond end of the fingerprint sensor and the third end of thefingerprint sensor, the process ends.

In specific implementations, because the first fingerprint is the sameas the pre-stored second fingerprint, after acquiring the inputdirection of the first fingerprint, the terminal matches the inputdirection of the first fingerprint with the input direction of thepre-stored second fingerprint, and then finds a corresponding screendisplaying direction according to the matching input direction of thesecond fingerprint. For example, if the terminal matches the inputdirection of the first fingerprint with the input direction of thesecond fingerprint illustrated in FIG. 4, namely, if the input directionof the first fingerprint is sliding form the fourth end of thefingerprint sensor to the second end of the fingerprint sensor, thecorresponding screen displaying direction is the vertical directiontowards the second end of the fingerprint sensor, so that the terminaladjusts the current screen displaying direction to the verticaldirection towards the second end of the fingerprint sensor.

As an implementation, as illustrated in FIG. 10, the terminal furtherincludes a recording module 907 (such as a memory unit) and a secondadjusting module 908 (such as a processor).

The recording module 907 is configured to record a time period foracquiring the first fingerprint when the first fingerprint is acquiredagain. The second adjusting module 908 is configured to adjust the sizeof the screen display area according to the time period for acquiringthe first fingerprint recorded by the recording module 907.

In specific implementations, after adjusting the screen displayingdirection, if the first fingerprint is acquired again, the terminalrecords a time period that the first fingerprint stays on thefingerprint sensor. For example, the first user can keep the right indexfinger pressing the fingerprint sensor, such that to make thefingerprint sensor record the time period that the fingerprint of theright index finger (namely, the first fingerprint) stays on thefingerprint sensor.

In specific implementations, the terminal can set a corresponding sizeof the screen display area according to the time period that the firstfingerprint stays on the fingerprint sensor. For example, if the timeperiod that the first fingerprint stays on the fingerprint sensor is onesecond, the size of the screen display area can be set to 75% of thescreen size; if the time period that the first fingerprint stays on thefingerprint sensor is two second, the size of the screen display areacan be set to 50% of the screen size; if the time period that the firstfingerprint stays on the fingerprint sensor is three second, the size ofthe screen display area can be set to 100% of the screen size. So thatthe terminal can adjust the size of the screen display area according tothe acquired time period that the first fingerprint stays on thefingerprint sensor.

The terminal can further includes a hardware processor, which isconnected with a memory through a bus for example. One or more programsare stored in the memory, and the programs can be used to implement allor part of operations of the above-mentioned methods of theimplementations of the present disclosure.

By means of implementations of the present disclosure, an authorityfingerprint is acquired, and the authority fingerprint is a fingerprinthaving the authority of changing a screen displaying direction; when afirst fingerprint is acquired, it is judged whether the firstfingerprint is the authority fingerprint, if so, an input direction ofthe first fingerprint is acquired and the screen displaying direction isadjusted according to the input direction of the first fingerprint.Besides, the authority fingerprint for changing the screen direction canbe preset. When the first fingerprint is acquired, if the firstfingerprint is the authority fingerprint, the screen displayingdirection is adjusted according to the input direction of the firstfingerprint, so that a timing for adjusting the screen displayingdirection can be judged accurately, and the accuracy of adjusting thescreen displaying direction can be improved.
